Abstract: 19,908. Gautier, M. Sept. 20. Water - waste preventers, tipping-tank. The flushing-tank is divided into compartments M and N, to the upper of which the service pipe c is connected. In the lower a tipping-tank R is mounted. When the closet seat is depressed, the rod T<1> in rising closes the valve S<1> and opens the valves upon the same spindle. The chamber M then fills. When the seat is again liberated, the valve S closes and S' opens. The chamber M then discharges into the tank R, which finally tilts and gives the flush. In a modification, Fig. 2, the tipping-tank is normally held in the position shown in broken lines by the lever D of the inlet cock S, which is closed. When the pull is operated, the lever D is raised, thus allowing the tank to assume the position shown in full lines. The lever D then drops, and opens the valve S. The tank fills and tilts, thus again raising the lever D and closing the inlet.

Title: Manufacture of Ionone from Citral and Acetone and of Cyclocitral as Intermediate Product.
Inventor: STREBEL ADOLF
Filed: 1898-11-04
Granted: 1899-09-02
Abstract: 23,254. Strebel, A. Nov. 4. Perfumery.-Ionone is prepared from citral and acetone by the following operations :-(1) Cyclocitral is first produced. For this purpose citral is condensed with cyanacetic acid, or a salt or ether thereof, in the presence of caustic soda' and alcohol, whereby citralidene cyanacetic acid melting at 124‹-122‹ C., or a derivative thereof, is produced ; then this product is converted into its cyclic isomeride by boiling it at a reflux-cooler with diluted sulphuric acid for twelve hours, after the manner described in Specification No. 22,114, A.D. 1893; and, finally, the cyclic compound, which after removal of bye-products is obtained as a syrup, is distilled in a powerful current of steam in presence of caustic alkali, and the distillate is fractionated to obtain crude cyclocitral as a yellowish liquid boiling at 80‹-110‹ C. under a pressure of 15 mm. The cyclocitralidene cyanacetio acid may also be hydrolysed by boiling it with caustic potash solution and xylene, and then separating and fractionating the xylene layer. A small quantity of a gentle oxidizing- agent, such as lead peroxide or the like, may advantageously be used in these hydrolysing operations. (2) Cyclocitral is condensed with acetone by means of alkaline reagents, for example, a solution of sodium in alcohol, at the ordinary temperature. The mixture is then neutralized by tartaric or other acid, and is distilled in a strong current of steam. On redistillation the fraction which boils at 130‹-140‹ C., under a pressure of 16 mm., is collected as ionone. It is rich in #-ionone, and yields a semi-earbazone melting at 148‹ C., and a p-bromophenyl-hydrazone melting at 116‹ C.

Title: Improvements in and connected with Oil Engines applicable also to Gas Engines.
Inventor: MELHUISH ALFRED GEORGE
Filed: 1901-10-21
Granted: 1902-10-16
Abstract: 21,102. Melhuish, A. G. Oct. 21. Gas and explosive-vapour engines, reversing. The engine is reversed by producing a premature ignition or otherwise increasing the load on the in-stroke. Fig. 1 shows a two-stroke cycle engine in which the piston uncovers the exhaust port at about half out-stroke and draws in a charge through the port C during the remainder. During the in-stroke the residual exhaust is expelled through the valves B, G, and the new charge is then compressed. To reverse the engine, an opposite cam J on the crank shaft is put in line with the valve G so that the valve is not opened on the in-stroke and the pressure rises high enough to produce a premature explosion. The valve G may be a piston valve worked through a link motion. Fig. 2 shows an engine of the type described in Specification No. 9038, A.D. 1895. At the end of the out-stroke some of the exhaust enters the vacuous annular space A<1>, the new charge entering the cylinder to take its place. The valve G controls the escape of the residual products on the in-stroke as in Fig. 1. The engine may be stopped on the in-stroke by compressing air in a cylinder without clearance, the valves of which are controlled by a link motion. The invention is applicable to yachts, motor cars, cranes, and the like.
